Add palmte board config bits for TSC2102 controlled devices. This will
enable touchscreen, audio and APM code to report battery level.

If there are other boards at some point that use a TSC2102, similar
code can be used.

General update of the board file for Palm Tungsten E. Registers the
platform devices contained in the PDA (ROM chip, keypad, infra-red)
and updates the configuration for USB and MMC, whose config values
were previously guessed in most cases due to lack of documentation
(and now are confirmed by a number of users). Macros for GPIO pins are
moved to a file in include/asm-arm/arch-omap.

Bugfixes for the OSK led support:

 - Fix Kconfig merge glitches:  Mistral handles idle and timer leds just fine
 - Fix pm_suspend() runtime botch:  can't sleep, so can't touch tps65010 leds

Improvements:
 - Switch sense of Mistral idle led, so idle == off

Probably the TPS65010 leds should be handled only by the "new led" API.

GPIO and MPUIO wake updates:

 - Hook MPUIOs into the irq wakeup framework too.  This uses a platform
   device to update irq enables during system sleep states, instead of
   a sys_device, since the latter is no longer needed for such things.

 - Also forward enable/disable irq wake requests to the relevant GPIO
   controller, so the top level IRQ dispatcher can (eventually) handle
   these wakeup events automatically if more than one GPIO pin needs to
   be a wakeup event source.

 - Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
   read-only data under the spinlock.

This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.

Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong:  omap1
saves the flags but ignores them, omap2 doesn't even save it.  (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

More GPIO/IRQ cleanup:

  - compile-time removal of much useless code
      * mpuio support on non-OMAP1.
      * 15xx/730/24xx gpio support on 1610
      * 15xx/730/16xx gpio support on 24xx
      * etc

  - remove all BUG() calls, which are always bad news ... replaced some
    with normal fault reports for that call, others with WARN_ON(1).

  - small mpuio bugfix:  add missing set_type() method

Partial fix for CONFIG_LEDS breakage ... at least allow platforms

Updating system time and reprogramming timer can cause latency
issues on busy systems with lots of interrupts with constant
updating of time and reprogramming the system timer.

If a non-timer dyntick interrupt happens within a jiffy from
the last interrupt, updating time and reprogramming the timer
is unnecessary as we will get a timer interrupt soon anyways.

This adds generic support for the "debug board" LEDs used by most of
TI's OMAP reference boards, and board-specific support for the H4.

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2.
Those should be able to switch easily to this version, and clean up
some of the omap1-specific code.

In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that
can be handy for kernel debugging), but it also supports the "new"
generic LED API (most useful for usermode stuff IMO).  Either or both
APIs can be enabled.
